Configuring Vlans and BPDU

[Sanjay916]

Hello, I am having trouble solving this network. How do I configure these requirements so that my network have full connectivity. 

• Configure all redundant links between Switch0 and Switch1 as an etherchannel
• Configure all Trunks to allow only Vlan traffic for the vlans in the topology
• Configure NAT ON INTERNET SWITCH
• Put all unused switchports into vlan 99
• Configure BPDU guard and Portfast on all switchports not connected to other switches or routers.

• Configure Switch 0 as the VTP Server
  VTP Domain = ndd43002

• Configure DHCP on Router0

I also included a config script of what i configure so far and also a screenshot of the topology. Please and Thank you.
